<u>Answer:</u> There are 9 hydrogen atoms in the given chemical formula.

<u>Explanation:</u>

We are given a chemical formula of ammonia which is NH_3

This molecule is formed by the combination of hydrogen and nitrogen atoms.

In 1 mole of ammonia, 1 atom of nitrogen is there and 3 atoms of hydrogen is there.

We are given:

Moles of ammonia = 3

So, 3 atoms of nitrogen is there and 9 atoms of hydrogen is there.

Hence, there are 9 hydrogen atoms in the given chemical formula.

The change in internal energy for the combustion of 1.0 mol of octane at a pressure of 1.0 atm is -5084.1 kj . f the change in e
TEA [102]

<u>Given:</u>

Change in internal energy = ΔU = -5084.1 kJ

Change in enthalpy = ΔH = -5074.3 kJ

<u>To determine:</u>

The work done, W

<u>Explanation:</u>

Based on the first law of thermodynamics,

ΔH = ΔU + PΔV

the work done by a gas is given as:

W = -PΔV

Therefore:

ΔH = ΔU - W

W = ΔU-ΔH = -5084.1 -(-5074.3) = -9.8 kJ

Ans: Work done is -9.8 kJ
